I felt strong and smooth from Mulholland to the M.A.S.H. site, and even up the first half mile of Bulldog. But before long, it was clear that the heat was getting to me, and I didn't have the reserves to power through. I completely cracked, and crawled the rest of the way up.
So, it's time for a back-off week. Next week I'll do a couple of easy recovery rides, a couple of short, sharp climbs (Rock Store, maybe Westlake), and get as much rest as I can. Gotta give my body time to digest all this climbing I've been doing.
